Following is the link to Google Analytics LAB which has some useful applications and plugins to enhance the usage of Analytics data. You can find plugins to Microsoft Excel to generate nicer reports as well as applications that allows you to embed Google Analytics reports into your web pages for the world to see.
These are not Google apps and Google makes no promises or representations about their performance, quality, or content, but some of them look useful
